JQuery :: Headers And Non JS Code Returned From JSONP Request?

So I have a function that is going to get a URL, and have to retrieve json data from that URL. The URL _might_ be same-domain, and might be cross-domain. If it's cross-domain, of course I want to do jsonp complete with the script-tag-to-load and such, but if it's same domain of course I want to do just xhr for efficiency. So I _could_ write all my own logic for this. Write logic to see if the url is cross-domain or not, and then make entirely different $.ajax() calls depending.
(I think I need to use $.ajax() rather than $.getJSON() because I need a callback on failure, not just success). If it is cross-domain, use dataType:jsonp, and make sure to supply a &callback. If it's not cross-domain, dataType:json, and don't even bother supplying a callback. But I'm having trouble figuring out if this is true, or how. What's the easiest way to get $.ajax() to make a dataType:json request if it's same-domain, but a dataType:jsonp request if it's cross-domain?
I'm using an .ajax() call to do a jsonp request to another domain. When the user is not logged in, however, the server will return a 401 error. Unfortunately, this causes my .ajax() call to fail _without_ calling the error callback. Is this a known bug? Here is my code:

I'm trying to access a web application that allows single sign-on when it is passed the following HTTP Request headers:

This script is within a blank webpage on my IIS server. Essentially, all the elements of the web app's UI get thrown within a div, but it doesn't seem to be loading the other parts of the page such as the <head>. I read on another thread that it is not a good idea to try and put everything within a div cause of the other html and head tags that already exist. Basically, what I want to do is access the webpage that has the above script and have it re-direct me to the Web Application's URL and adding in the custom HTTP Request headers.
I am submitting a form using ajaxSubmit and trying to read back the status code.For a error case it is showing HTTP Status 404 in responseText but not xhr.status is undefined.If i use complete callback then xhr.status 0 So how to handle case when there is some error like 404..[code]
View 2 Replies View RelatedI want to update an element in my DOM that contains Javascript code when an action X is performed and an AJAX response generated with new Javascript code that is one of the AJAX response variables.
The AJAX request is successfully returned, as is the Javascript JSON response variable. However, I'm having no luck updating the DOM element containing the old JS code with the new JS code. I'm performing these operations using JQuery.
I am trying to xmlhttp object using ajax. In my first request I am getting the desired result. On the readystatechange I called a function whic process the response of the first request. According to the response of my first request, I fired the second httprequest. But the second httprequest always returns a status code 0. I got a message called request cancelled.

I worked with now in jQuery. Property however at present the following problem: [i]I provide a AJAX Request. the side is loaded, the parameters all conveyed and back receives I a complete HTML side. Now I would like to have only certain elements however from this side, like DIV, SPAN etc. How can I make with the AJAX Request return in such a way best, which I can select these elements thereby? Simply it would be unfortunately not functioned over the function $ (element), it even if I indicate the HTML Request as secondly parameter.[/i] Excused, for my bad English. ;-) Translatertool. There is unfortunately too many words, in order to describe my problem. ^^
View 2 Replies View RelatedCurrently I was able to load remote JSON (php) file using JSONP protocol. However, how to do if my remote file is static? In the doc, it said: you can load JSON data located on another domain if you specify a JSONP callback, which can be done like so: "myurl?callback=?". But since my remote file is a static text file, how can I specify the callback in the output dynamically? In fact, I also wonder if it is possible to control the random callback name by modifying jquery source code...

I am needing some help with an error I'm getting from a project I'm working on. First off let me preface this all with the fact that I'm a total javascript noob. I'm really trying to understand what I'm doing wrong. So any help or advice is MORE than welcome. Here's what is happening. I found this code that will duplicate a row in a table and modifiy the name of a input in the row. Well for my purposes I have two different tables I need to work with. (each one idividually) So I changed the code a bit to make it accecpt a variable to use for the table name. (before it was static) and now I'm getting a error. Error: uncaught exception: [Exception... "Component returned failure code: 0x80004003 (NS_ERROR_INVALID_POINTER)" nsresult: "0x80004003 (NS_ERROR_INVALID_POINTER)" location: "JS frame :: http://www.tourandtravelnow.com/admin/scripts/faxPageScript.js :: addRow :: line 14" data: no] This is the old code that would work (only for one of the tables)

I found this post: [URL] It explains exactly what I want to do. The person who had the problem seemed to have sorted it out but as my knowledge is not to great I am not to sure what he is getting at. I tried various things but to no avail. All I want to do is return data to a calling javascript using type get and datatype jsonp. If I simply Response.Write "[(""id"": ""123""}]" then nothing happens. So whatever the thread I revered to above is doing it seems to be going in the right direction.

$( document ).ready( function(){
$('#get_metars').click( function(){
//var icao = $('#icaos').val();
[code]....
If this is synchronous, normal json request, I can capture the result (data) and return it to a calling function.
However jsonp is not synchronous. Whilst the data IS returned, and I can view it from within the success function, but I cannot access it after that.
$.ajax({
url: remote_url,
async: false,
cache: false,

I am building a library of functions which call this function, so I cannot have the data processing done within the success function, I need to extract the data itself.
I am trying to develop a iGoogle-like dashboard that uses JSONP to get the content of each widget from other (trusted) sites.Each widget is a div that will take care of getting its content using $.ajax() and use the callback to update the div with the html content returned with JSONP.The problem I have happens only in Firefox (I'm using 3.6.3):when a site is unavailable or takes longer to return the JSONP content for a widget, it seems that the callback for the other widget does not get executed. All the widgets stay in the "loading" state although I'm sure they have all received the answer.What's puzzling is that if I hit the "stop" button of Firefox, the content of the other widgets get displayed (ie. their displaying callbacks get executed).
If the calls are asynchronous, what prevents Firefox from executing the callbacks for the other widgets once the response is received?Do you have any idea of what's happening and if there's some way around this?
I have some jQuery making ajax requests that works just fine if the server returns a 200 but whenever it returns any error HTTP status none of the events fire. It's happening on more than one request to different servers but I'll just include one example for now:
var ajaxResponse = $.ajax({
url: widget.serviceURL + 'customer/createAjax?'+$('#ndBookingFormStep1').serialize(),
dataType: 'jsonp',
success: function(data, textStatus, jqXHR){
console.log(data);
if( data.status != 'OK'){
widget.message(data.status);
} else {
console.log(data);
}}})
.error(function(jqXHR, textStatus, errorThrown){
console.log(jqXHR);
}).complete(function(jqXHR, textStatus){
console.log(jqXHR);
});
console.log(ajaxResponse);
console.log(ajaxResponse.responseText );
The request gets made just fine, I can see the response in the net console in firebug and it returns the data I want with a 500 when I do not complete the form correctly. However, it does not fire either the error or the complete function when I get this status, and the ajaxResponse.responseText is undefined when it is logged to the screen. When the form is completed and the request is successfull the success function fires just fine.
I'm tryng to develop a link tracker, something like google analytics. The goal is to get a command like this:
$('html').trackAllLinks(optional options);
$('a').trackAllLinks(optional options);
Now i developed a javascript that could do just what i need but the problem is it doesn't work in every browser as it should be. Because i want to track a link click i need to make a request to my server to say that the link has been clicked. The first problem i had was that i needed to make a cross domain ajax call. But this is fixed by using JSONP. Now my code looks like this:
[Code]...
The first idea was that i wouldn't do anything in the success of the jsonp call and just let the request go, but because this didn't work when i clicked on an external link, i changed it to wait on a response before opening the link. The problem with this code is that it doesn't work in Opera, no request is being send to the server Now i know that JSONP mimics the ajax call by adding a script tag to the page which loads the script of the given url. Now i think when i do this in Opera the dynamically loaded javascript isn't executed. In Firefox, IE, Chrome, Safari it works but not in Opera.
Another idea i had was by dynamicly adding an image to the page. But this has the same problem in Opera and i was unable to track an external link in Safari and Chrome (Webkit.
I have jQuery 1.5.1 client-side that is making an .ajax() call to an ASP.Net MVC controller method - expecting a jsonp packaged response. In normal cases, the server packages up a response of typeapplication/json and that works fine. The problem is when the session on the server times out, the server will respond to the ajax call with the server's login page, which obviously isn't valid json and the error handler on the ajax call fires with a parseerror. Similarly, if there's an exception server-side, the site redirects to a custom error page, which again isn't valid json, and: barf. I have no information client-side what went wrong when in the .ajax error handler. The xhr just says parseerror with no further info. Is there any way I can see what the server responded with so I can handle this more intelligently? I've tried change the client-side dataType to "json text" hoping that it would try to interpret the server response as text, if the json fails, but it just goes to the error handler.
View 4 Replies View RelatedI'm trying to use .load to get a simple web page. In the documentation for the .load function, I see that I can just return parts of page. I pass through the <body> element in order to just get the body, and not the headers of the html document, however in FireFox, it seems to still be returning all the headers. How can I use .load to ignore the headers.
View 4 Replies View RelatedI am submitting a form via AJAX. The form may either return HTML (when there are input errors) or JSON (successful response). If during request I specify "dataType: 'json'" then HTML doesn't get thru correctly, if I don't then JSON is displayed as plain text. I am sending the "application/json" header back correctly. I don't understand why doesn't jQuery just pick that up and parse it as JSON? Is there an option? Is there something I can do to make this work?

I have a php page which returns a table representing a query sent to a MySQL database. So far it has worked in every case except now that I'm trying to use it to call a stored procedure, in which case the readystate is staying at 1 and never completing.
I have logged the results of the php file both in an error log and looked at the response from the request using firebug, both of which show a correct result.
Why isn't this returning properly?
Here are the relevant javascript functions:
Code:
function customizeType()
{
$("custom-header").innerHTML = "";
$("custom-top").innerHTML = "";
[Code]....
After the page loads, the error log shows correct results for all queries.
I am using .ajax() to access cross-domain data using JSONP. Because I need to be able to cache the data I want to use a static name for thejsonpCallback function, so I have set the jsonpCallback option in the .ajax() request. However that appears to requires a global function whereas the auto generated function didn't (well maybe it did but that was all hidden from me).
I definitely need to be able to cache the results. Ideally I wouldn't have a global function handling the data. Is there another way to do this? If not what is the best practice way to go about using a global function these days and how do I provide it with the context of the object/module it was called from - which is where the data is needed?
I have a div with headers. Of course, when there are too many rows, you have to scroll and lose the headers of the form. How can I accomplished "fixed headers?" so that they're always visible?
